    Find the k value of vertex (h, k) for the equation y equals 6 x squared plus 24 x plus 2.

    The other method to find the vertex of a parabola is as we know that the x-coordinate of a vertex, (i.e) h is -b/2a.Now, substitute the x-coordinate value in the given standard form of the parabola equation y=ax2+bx+c, we will get the y-coordinate of a vertex.
